EmIT: Emotional Interaction control in Text-to-image diffusion models
Abstract
Although current work of text-to-Image generation can preliminarily generate images from the descriptions of human-object interactions, it fails to consider the emotions involved in human-object interactions. While people often experience emotions when using objects or interacting with them. Therefore, in this paper, we propose Emotional Interaction Generation task, a novel image generation task, which generates emotionally expressive human-object interaction images from given prompts, human-object interaction (HOI) region, and emotions. First, we construct a new emotional interaction dataset, called EmotionHOI, which including 47,776 images with content prompt, emotions and human-object interaction bounding box. Second, we propose an emotion-aware text-to-image diffusion model, named EmIT, for emotional interaction generation. Specifically, EmIT consists of three components: (1) an emotion interaction tokenizer that encodes subject, object, action, and emotion into structured tokens; (2) an Emo-Interaction Self-Attention that preliminarily guides the latent space to conduct hybrid learning with emotional interaction tokens; and (3) a Hierarchical Emotion-Visual Cross-Attention that further focus on grounding affect-such as pose, gaze, or interaction intensity-into specific spatial regions and capture subtle emotional variations. These components jointly model interaction semantics and emotional context, enabling EmIT to generate images that are both behaviorally coherent…
